malloc is complaining that you have corrupted a pointer in some way example:
The error happens on a realloc or a free because the pointer no longer references the same start of memory. You can get the same result by writing, say, 15 characters into the tmp string, so that you overwrote the string and changed the memory value stored in ptr.

Hi
I have a strange phenomenon on putty session connected to RHEL4 server.
My session is active but without any activity for 2 or 3 hours and suddenly this message appears on the prompt :

Could you have an idea about it ? (2 Replies)
Here is a simple program to find the vowels in the string.
Output is fine.
But I'm getting GLIBC detected as shown below : :eek:

Hello,
I currently have glibc 2.13. I was wondering if you could teach me how to switch to : glibc2.3.2
I would really appreciate it if you tell me how to do it step by step since I am a beginner .
thanks. (1 Reply)
I come across the following error while configuring glibc 2.16.0 on ubuntu 12.04 LTS:"These critical programs are missing or too old: ld". Please suggest me a solution for the same at the earliest. (1 Reply)

sched_getcpu
SCHED_GETCPU(3) Linux Programmer's Manual SCHED_GETCPU(3)NAME
sched_getcpu - determine CPU on which the calling thread is running
SYNOPSIS
#include <sched.h>
int sched_getcpu(void);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
sched_getcpu():
Since glibc 2.14:
_GNU_SOURCE
Before glibc 2.14:
_BSD_SOURCE || _SVID_SOURCE
/* _GNU_SOURCE also suffices */
DESCRIPTION
sched_getcpu() returns the number of the CPU on which the calling thread is currently executing.
RETURN VALUE
On success, sched_getcpu() returns a nonnegative CPU number. On error, -1 is returned and errno is set to indicate the error.
ERRORS
ENOSYS This kernel does not implement getcpu(2).
VERSIONS
This function is available since glibc 2.6.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

|Interface | Attribute | Value |

|sched_getcpu() | Thread safety | MT-Safe |
+---------------+---------------+---------+
CONFORMING TO
sched_getcpu() is glibc-specific.
NOTES
The call
cpu = sched_getcpu();
is equivalent to the following getcpu(2) call:
int c, s;
s = getcpu(&c, NULL, NULL);
cpu = (s == -1) ? s : c;
